Principles of War by Sun Zi

English: Thus, if the schemes and ploys of the neighbouring warlords are not known, one should not be keen to enter into any alliances with them. Those who do not know the conditions of forested mountains, the dangerous terrain of mountain paths and the treacherous nature of swamps and marshes will not be able to conduct the movement of troops. Those who do not use local guides will not be able to gain the advantages of the terrain.

Modern: 所以，不知道诸侯的谋略，不能与之结交；不知道山林、险阻、沼泽等地形，就不能行军；没有向导，则不能得地利之便。

Original: 是故不知诸侯之谋者，不能预交；不知山林、险阻、沮泽之形者，不能行军；不用乡导者，不能得地利。
